The HiPro system
Operator's Manual GB
4.2
On remote controlled cranes prohibited move-
ments are stopped.
On manually operated cranes, all movements
are stopped, because when a spool is moved
too much, power to the dump valve is cut, all
movements are stopped.
Fault monitoring
When there is a fault in the control system it will
give an immediate warning.
Depending upon the fault the crane speed and/or
the load capacity will be reduced. When the fault
is serious, use of the crane is blocked completely.
DANGER
Never try to repair the control system yourself.
Repairs may only be made by a HIAB service
workshop!
